STAMP-CANCELING DEVICE.

SPECIFICATION forming part of Letters Patent No. 233,769, dated October 26, 1880,

Application filed May 11, 1880. (N0 model.)

have invented certain new and useful Improvements in Postage-Stamp-Qanceling Devices; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

The nature of our invention consists in the construction and arrangement of a device for canceling stamps, as will be hereinafter more fully set forth.

In the annexed drawingsfl igure l is a side view of our stamp-canceler. Fig. 2 is a longitudinal section of the same, and Figs. 3, 4, and 5 are detail views of parts thereof. Fig. 6 is a cross section just below the headblock B.

A represents the handle, made of brass or other suitable material. This handle is hollow, its lower end being open, while the upper end is closed and rounded.

In the lower end of the handle is a crosshead or top, B, for the passage of the screw 0, said cross-head having lugs (a a, which are fastened to the handle by screws b I), thus holding the cross-head in place.

D is a hollow chamber placed within the handle A, and provided with longitudinal slots 00 00, to pass over the lugs a of the crosshead and allow said chamber to extend below the same.

The lower end of the chamber D is provided with exterior screw-threads, on which is screwed the nose-band E. This nose-band is provided with an interior shoulder, 0, upon which rests a rubber or other washer, d, and on top of this washer is a bisected journalbox, F, fitting around a journal, i, formed between two collars, h h, on the lower portion of the screw 0, said journal being a continuation of the screw.- "On the lower end of this screw is fastened the head G, which revolves in the nose-band. This head is provided with a central nose-piece, m, and has also two knives, n n, screwed into it from the under side, said knives being held from accidental displacement by jam-nuts p.

A spiral spring, I, surrounds the screw 0 within the chamber D, as shown. By press ing down on the handle D the screw 0 passes up through the cross-head B, and must, of course, rotate therein, and as the head G is attached to the lower end of said screw the head must rotate with it. As soon as the pressure is removed from the handle the spring I throws the parts back into their former positions.

The disk or head G, which holds the knives, is sufficiently removed from the stamp to avoid friction, except so much of the center as is sufficient to hold the stamp while it is being out with the knives, this center portion being the nose-piece m.

The canceling is a clear out, and as the stamp is gummed to the envelope the severed portion of the stamp remains thereon, though out entirely through.

It is immaterial whether or not the envelope be of the same thickness as the stamp, as the knives will do their work as well on one thickness as another, cutting only where they touch, whereas in devices which scratch or tear, if the envelope be thinner or weaker than the stamp, it (the envelope) will tear first.

The knives can be readily replaced and sharpened or new ones substituted without taking the machine to pieces, and they can also be adjusted or regulated to cut any depth by turning the screw-shanks of the knives so as to make the knives project more or less below the head, the knives being then held, as stated, from accidental displacement by the jam-nuts p.

The machine mayalso have the ordinary postmarking device attached to it on one side, so that the marking and cancellation willbe done at one time.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-
